问题 Does anyone else there have any issues with a very sluggish development experience in VS 2015 writing apps for the Universal Windows Platform 10? Compiling, debugging, even switching between windows is painfully slow compared to working with a similar, basic WPF application. I have not been able to find any mention of this experience on Google, which leads me to wonder if there's something in my setup that is throwing a monkey wrench into UWP dev. Has anyone experienced this, or know of any

问题 When uninstalling programs I see hundreds of packages with the name "NoUIEntryPoints-DesignMode". As a result of my research I have recognized if you debug an UWP-App which registers a file extension it will create this package and the system is not able to delete it. How can I delete them all? At the moment the "Apps & Features"-Page looks like this: 回答1: You can use the following PowerShell command: Get-AppxPackage -Publisher "CN=Microsoft Corporation, O=Microsoft Corporation, L=Redmond, S

问题 Have the latest releases to Windows IoT included an On Screen Keyboard? I am aware of other suggestions that use the webview to provide a keyboard, but I would prefer an OSK for my UWP app. Ideally internationalised. 回答1: On Screen Keyboard is not mentioned in the latest release 14931, so the answer is no at the moment. Part of the reason for this is that we don’t have a ‘shell’ like explorer that is there helping control what app is running or providing other services such as SIP / OSK as is

问题 I have set a bool property and have bound it to the IsEnabled in the xaml but the ICommand CanExecute method overrides the IsEnabled in xaml, so my bool property is ineffective. When I define the conditions within the CanExecute method in the view model, It either disables all buttons in which the method is bound to, or enables all of them. Its a grid that displays 3 different buttons for each row, and each button goes to a new xaml screen. If there is no data for the particular condition on

问题 I have the same problem as this guy over here: UWP Timetrigger not working but I can't comment the question because my reputation is not high enough, so I'm creating a new question. As I said, I have the same problem. I registered the background task, but nothing happens. My background task is located in a seperate project (Runtime Component). So that's not the problem. This is the method I made to register the task: public static BackgroundTaskRegistration Register(string name, string

问题 I am developing an image processing app for windows 10. I have searched online related to the image processing. I have found many resources that use Bitmap class for manipulating images. But in uwp, there is no such class exists. When I try to use it in my code, it says Generate Bitmap class. Is there any alternative to this class in uwp? Or I am missing any reference of Bitmap class? 回答1: I was developing an app not so long ago that needed the features of the Bitmap class. I sadly realized
